a2nr 9918aafe41 fix: Phase B — readValue() state poll fallback for END ACK ... Firmware: - Add BLE_GATT_CHR_F_READ to flashing characteristic - Read callback returns state_machine_get_current() as 1 byte (4=SERIAL_BRIDGE=success, 5/6=ERROR) Frontend: - Replace ineffective pendingAcks poll with readValue() poll - CCCD refresh fire-and-forget (non-blocking) - Race ackPromise (notify) vs readPoll (readValue) - Clean up ackPromise resolver on readPoll win - Cache v7 → v8		2026-06-30 17:35:23 +07:00
